    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 LR$z0rDEM  
    -gKpL\  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: r*cjOrvI  
    enableservice('AutomationServer', true) kG3!(?:  
    enableservice('AutomationServer') dm^H5D/A  
    !7` [i  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 2bA#D%PHD  
    `facFt[\  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: ujx-jIhT_  
    1. 在FRED脚本编辑界面找到参考. { R*Y=Ie  
    2. 找到Matlab Automation Server Type Library 3&J&^O  
    3. 将名字改为MLAPP 5 ;vC(Go

    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 nu 7lh6o=

    现在将脚本代码公布如下,此脚本执行如下几个步骤: w#{l 4{X|  
    1. 创建Matlab服务器。 :,C%01bH|l  
    2. 移动探测面对于前一聚焦面的位置。 ze"~Ird  
    3. 在探测面追迹光线 i]M"Cu*  
    4. 在探测面计算照度 -lp"#^ ;  
    5. 使用PutWorkspaceData发送照度数据到Matlab 5^|"_Q#:  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 U?6yke  
    7. 用Matlab画出照度数据 g3a/;wl  
    8. 在Matlab计算照度平均值 jT"r$""1d  
    9. 返回数据到FRED中 FU]4oKx
